The Bitcoin-Backed Stablecoin That Ditches US Treasuries with David Seroy
7/10TL;DR
Developers are advancing Bitcoin-backed, censorship-resistant stablecoins to challenge dollar-pegged tokens tied to U.S. Treasuries.
KEY POINTS
Stablecoins Show Clear Demand
Stablecoins have established strong product-market fit, particularly in regions lacking reliable banking infrastructure. Their ability to offer price stability makes them more practical than volatile cryptocurrencies for everyday transactions. Dollar-pegged tokens such as USDC and Tether (USDT) dominate usage, highlighting widespread demand for predictable digital value.
Reliance on U.S. Treasuries Raises Concerns
Most leading stablecoins are backed by U.S. Treasuries, creating both centralization and censorship risks. Issuers retain the ability to freeze or control funds, even if used sparingly. Critics argue that growing demand for these assets indirectly supports government debt markets, reinforcing the traditional financial system that decentralized currencies aim to bypass.
Tension With Bitcoin’s Ideology
Within the Bitcoin ecosystem, reliance on Treasury-backed stablecoins is viewed as contradictory. Increased adoption of such tokens may strengthen fiat-based systems rather than disrupt them. This dynamic has fueled interest in alternatives that align more closely with Bitcoin’s decentralization goals.
Past Attempts Exposed Structural Weaknesses
Earlier crypto-collateralized models, including MakerDAO’s DAI, initially relied on assets like Ethereum but later incorporated centralized collateral such as USDC. Algorithmic approaches, most notably TerraUSD, collapsed entirely. These failures highlighted the difficulty of maintaining stability without introducing centralization or fragility.
Liquity Model Introduces Immutable Design
The Liquity protocol represents a newer approach, offering a stablecoin backed by crypto collateral with no governance or upgrade controls. Its system is designed to be immutable, removing the possibility of administrative intervention. Over several years, it has maintained its peg while avoiding reliance on centralized assets.
Stability Pool Replaces Liquidation Auctions
Liquity replaces traditional liquidation auctions with a stability pool, where users deposit stablecoins to absorb undercollateralized positions. When liquidations occur, deposited tokens are burned and participants receive discounted collateral. This mechanism has proven efficient during periods of extreme volatility, avoiding congestion and delays seen in earlier systems.
Bitcoin as Preferred Collateral
Developers argue that Bitcoin is uniquely suited as collateral due to its liquidity and scale. Unlike smaller or more volatile assets, Bitcoin can support large issuance volumes, potentially reaching billions in circulating stablecoins. Its market depth is seen as critical for long-term sustainability.
Integration With ZK Rollups
Efforts are underway to bring Bitcoin into more expressive environments through zero-knowledge rollups. These systems aim to enable advanced financial logic while preserving Bitcoin’s security guarantees. By deploying immutable protocols on such layers, developers seek to create stablecoins that inherit Bitcoin’s resistance to censorship and double-spending.
Incentives Sustain the System
Participants in stability pools earn returns through liquidation gains and protocol interest. Newer designs introduce user-set interest rates, allowing borrowers to choose their borrowing costs. This flexibility, combined with liquidation rewards, is intended to maintain sufficient liquidity in the system.
Privacy Use Cases Drive Demand
A key anticipated use case is the intersection of privacy-preserving payments and stable value. Emerging technologies such as Fedimints and Cashu enable private transactions, but require assets that cannot be frozen or tracked. Censorship-resistant stablecoins are viewed as essential for these applications.
Bridging Remains a Technical Hurdle
The main challenge lies in securely moving Bitcoin into programmable environments and connecting stablecoins to privacy systems. Trust-minimized bridging solutions using zero-knowledge proofs are advancing, but remain in early deployment stages. Reliable infrastructure is necessary before such systems can scale.
CONCLUSION
Bitcoin-backed stablecoins aim to reconcile price stability with decentralization, but their success depends on overcoming technical barriers and competing with entrenched, Treasury-backed alternatives.
